ATTD RN EYS Patented June 6, 1950 UNITED STATES PATENT OFFICE HANDREMOVER FOR CLOCKS AND INSTRUMENTS 1 Claim.

This invention relates to improvements in implements for use inrepairing clocks and like mechanisms, and more particularly to a devicefor conveniently removing the hands of the clocks or like mechanisms.

An object of the invention is to provide a device which is simple inconstruction and operation, and which is adapted to remove the hands ofclocks or like mechanisms without damage to the arbor on which the handsare mounted or without damage to the mechanisms carrying these hands.

Other objects and advantages will become apparent as the invention isfurther described, claimed and illustrated in the accompanying drawingin which:

Figure 1 is a side elevational view of an embodiment of the invention ina position to remove the hands of a clock or like mechanism;

Figure 2 is a vertical sectional view on the line 2-2 of Figure 1;

Figure 3 is a cross sectional view on the line 3-3 of Figure 1;

Figure 4 is a detailed fragmentary cross sectional view on the line 4-4of Figure 1;

Figure 5 is a detailed fragmentary view, partly in section, of the screwand the removable tip therefor, and

Figure 6 is a plan view of the blank from which I the device is formed.

Referring more in detail to the drawing, the implement embodying theinvention is designated by the reference numeral ID. The implementcomprises a yoke II, which is formed from the blank shown in Figure 6.The yoke l I comprises a base portion 12, provided with a V-shaped slotl3, so formed that the apex of the V is inwardly of the forward end ofthe base portion. The ends of the base portion formed by the slot areinwardly and downwardly bevelled as shown at M. The bevel permits thebase to be inserted under the hands l5 and I6 that are connected to thearbor ll of the mechanism [8.

At the rear of the base portion, the yoke is bent upwardly along thedotted line 49 to form the vertical portion 20. The portion 20 beingbent on the dotted lines 2| and 22 respectively forms the parallel arms23 and 24 respectively. These arms overlie the base portion 12, and arespaced from the base portion in parallel relation thereto by the wings25 and 26 formed on the arms at the rear ends thereof.

Each of the arms is provided with a longitudinally extending elongatedslot 21, which are in alinement with each other on a horizontal plane.

Slidably mounted in the slots 27 are the reduced portions 28 of thescrew supporting block 29.

The block 29 has a centrally located tapped bore 30 to receive the pressscrew 3|. The screw 3| is provided with a knurled knob 32 on the upperend thereof, whereby the screw is manipulated. The lower end of thescrew is received in the tapped socket 33 of the removable bearing tip34.

The block 29 being slidably mounted in the slots 21 by reason of thereduced portions 28, the block can be moved with relation to the arborll until the tip 34 will bear evenly on the arbor H.

In use, the base is inserted under the hands l5 and It, as shown inFigure 1. The screw 3! is moved downwardly until the tip 34 is bearingevenly on the arbor ll. The block 29 being movable, a true alinement isachieved between the arbor I l and the tip. By further turning of theknob 32, the base portion I2 is moved upwardly, pulling the hands fromthe arbor.

It is believed that from the foregoing description, the construction andmanner of operation of the implement will be apparent to those skilledin the art, and it is to beunderstood that changes in the minor detailsof construction, arrangement and combination of parts may be resortedto, provided they fall within the spirit of the invention and the scopeof the appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

A tool, comprising a yoke, having a base portion, a vertical portion,arms on said vertical portion in parallel alinement with each other andin elevated parallel alinement with said base, a V- shaped slot in saidbase portion and the edge of the base outwardly of the slot beinginwardly and downwardly bevelled, parallel alined slots in said arms, ablock movably mounted in said slots, a screw having a removable bearingtip on its lower end and a knurled knob on its upper end threadablymounted in said block for movement away from and toward said baseportion.
